Scruggs says the messages included detailed instructions from Jones on how to prepare for sex.

Detectives monitored the exchanges as Jones drove from Union City, where he’s in college, and arrested him outside the family’s apartment. He allowed police to inspect two cellphones, one of which had access to a folder Scruggs says contained child pornography.

Jones is charged with several counts, and police are still investigating. It’s unclear whether he has a lawyer.
